      @neiltyson how is it that an insect flying within a bus, and not attached to any physical thing is not hit by the back of the moving bus?

      @agan83 Air in a closed bus moves at the same speed as the bus itself. If the bus had no front&rear the insect would sail right out the back

          @neiltyson @agan83 the laws of physics also apply when the same experiment is conducted with farts. A more common test, in my experience.

          @neiltyson @agan83 This is a great occurance. Vomiting on a rollercoaster vs. on a bus. You know which of the two is more fun.

          @neiltyson @agan83 @drkeevil I think this answers your "does train move underneath me if I jump while train is moving" question. I think.

          @neiltyson @agan83 ...and if the bus had no air (i.e., vacuum) the bug would hit the back also!

          @meshkalam @neiltyson @agan83 would the bug even be able to fly in a vacuum? Or, you know, live?

          @RichPhelps Wings are pointless in a vacuum. A bird or fly mite as well be a rock in space. I heard Dr. Tyson say that on Startalk

          @neiltyson @agan83 So, same deal if you throw a ball into the air inside the moving bus? It would come straight back down?

          @JGCanada @neiltyson @agan83 The ball has the same horizontal velocity as the rest of the bus so relative to you it comes straight down.
